SPECIFICATION.

IO ALL WHOM IT MAY CONCERN:

Be it known that I, J. C. FAY, of the city, county, and State of New York, have invented a new and improved Wind Wheel; and I do hereby declare that the following is a full, clear,'and exact descriptionA thereof, which will enable others skilled in the art to malle and use the same, reference being had to the accompanying drawings forming part of this specification, in 'which-` i Figure l is a vertical section of my invention taken in the line :v x, lig. 2.

Figure 2, a horizontal section of the same, taken in the line :j y, tig.. 1.

Figure 3, a front view of the upper part of the same.

Similar letters of reference indicate like parts.

This invention relates to a new and improved self-regulating windmill, or one which will rotate with equal or uniform velocity howeverfrihequal or irregular the velocity of the wind may be. The inventionl consists of two vertical wheels enclosed within a case having a vane attached to keep the front of the case facing the wind,

*the wheels being'connected withv each other and to a shaft, from which the power is taken by gears, and the front end o f the case provided with doors which are connected with a regulator; all being arranged as hereinafter fully shown and described, whereby it is believed that a simple, economical, and efficient windmill is obtained.

- A represents a box composed of a bottom, a, two upright parallel sides, bt, and a top, c, the-front and rear ends being open. The front ends of the bottom and top plates, a e, of the box are bevelled at each side of their centres, so as to have projecting points, which are connected by an upright, B, to -which two doors,` C C, are attached by hinges, d d, which open as they are shoved inward, and close the front end of the box when moved outward. l

These doors, C C, are connected by arms, e e, to a slide, D, which works on a horizontal guide, E, attached to an upright,f, in the box A, and in the upper end of said slide the lower end of a lever, F, is fitted, the latter having a roller, g, upon it, which is fitted loosely in a vertical recess, it, in the slide D. The lever F, has its fulcrum-pin, z', passing lthrough a horizontal arm, j, attached to the upright, in box A, and the upper end of the lever, F, is pivoted to the upper end of an arm, Z, the'lowe'r end of which is pivoted to the lower arm of a bent lever, Fl, having its fulcrum-pin, m, in the lower part of a pendant, n, attached to the top, c, of the box, and the upper arm of the'bent lever is pivoted to the upper end of an upright, o, the lower end of which is pivoted to a lever G, connected with a `ball-governor, H, as shown clearly in fig. 1.

I I represent two vertical wind wheels' placed side by side within the box- A. 'These wheels are composed of a seriesuof wings or blades, 1o, attached to shafts, q, which have their bearings in the top and bottom plates of the box A. The wings or blades p -,may have a radial position with the shafts q, or an oblique or tangential position. The radial position, however, will probably be as desirable as any. I

The lower ends of the wheel shaftsA g g, above the bottom, b, of the box, have toothed wheels, r, upon them which gear into each other, and the shaft g of one ofthe wheels below the bottom, b, has a toothed wheel, QI, upon it, which gears into a pinion, `K, on the upper end of a vertical shaft, L, from which shaft the power ii taken.

The shaft L passes through'a fixed base, M, on which the box A rests, and is allowed to turn freely from the top of the shaft L as a centre, the box A having rollers, s, attached to it to work on an annulal way or guide, t, on the base M. Y

To the' top of the box A there is attached a vane, N, partially shown, w/hioh keeps the frontend of th box A, where the doors C C are hung, facingthe wind.

The lower end of the governor-shaft {,belowthebottom, a, of the box, has a pinion, u, upon it, whicl gears into a wheel, v, the latter gearing into the wheel J on the lower end of the wheel shafts q.

The operation is asV follows:

The front end of the box A is kept facing the wind bymeans of the vane N, and thel wind passes into th front end of the case and impinges against the wings or blades p of the wheels I I, near the sides, I) b, of th box A, the doors C C serving as dellectors orA guides for the wind, as shown clearly in iig. 2. Thepower o the two wheels I I is transmitted to the shaft L through the medium of the gearing described, 'and the gov ernor,1.Hf,-1being rotated bythe gearing from the wheels I, the doors C C will be opened `or closed in a greate' @greg-,according to the velocity of the wind. As the velocityof the wind increases, the wheels I increase it speed, and consequently the governor; and, as the balls of the governor rise,"the doors G C, owing to the connection of the lever G with the doors C C, as shown and described, will be shoved forward nearer to a closed state, the doors being movedmore open as the wind decreases in velocity, and the balls of the governorrfall.`

Thus it will be seen that the spe'ed of the wheel will be rendered uniform under diii'erent degrees of velocity of the wind. It will also be seen that the turning of the box A to face the wind will not a'ect in the least any of the working partsl of the device. v

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The two vertical wheels I I, placed side by side in thebox A, connected with each other by gears, 1 r, and to a power-shaft, L, by gears J, K, substantially as and for the purpose set forth. 4

v 2. In combination with the wheels I I the doors C C, applied to the front end of the box A, as shown, so as to open and close, and admit of a greater or less amount of wind to pass through the box and act upon or against the wheels, as set forth.

. .3. The governor H, connecting with and receiving its motion from the wheels I l, and connected'wlith the doors C C, as shown, or in any equivalent way, so that the doors 'will be opened and closed, and the speed of the wheels rendered uniform under variable-degrees of velocity of the wind, as set forth.

4. Thev power-shaft L, connected by a pinion, K, andtoothed wheel, J, with the wind wheels I, in combination withthewbase M, provided with the annular wayt and thel box A, having rollers, s, attached to its underside, t'o work on the way substantially as and for the purpose specified.
